Paper aims This study develops a comprehensive theoretical framework and provides empirical evidence on the determinants influencing sustainability behaviors among Indonesian construction firms. Originality This study addresses a critical research gap by integrating two major theories to explain organizational-level adoption of sustainability in the construction industry. By extending these theories with context-specific factors, the study provides a novel, locally relevant model. Research method Data were collected via a self-administered cross-sectional survey employing purposive sampling. Of the 164 firms invited, 76 valid responses were obtained (46.3% response rate). The proposed model was tested using Partial Least Squares Structural Equation Modeling (PLS-SEM). Main findings multiple pathways to the adoption of sustainability in the Indonesian construction industry are observed. Notably, facilitating conditions are related to behavior, underscoring the critical role of institutional support in translating intention into practice. Implications for theory and practice This study broadens behavior theory beyond individual decision-making. This study reconfigures the TPB/UTAUT frameworks to explain organizational-level sustainability adoption by incorporating institutional pressures through a regulatory framework and introducing sustainability awareness as a context-specific antecedent. The results also suggest that effective policies, increased awareness, leadership commitment, and supportive infrastructure are essential for translating sustainability intentions into real action.

Introduction: Many companies, including PT PLN Group, use asset management to help manage their assets to achieve stable, effective, and efficient company performance. In the concept model introduced by IAM, companies are introduced to six subject groups that are important factors in asset management (AM) implementationMethods: This study used the PLS-SEM test to measure the level of influence and relationship of six non-formal factors and six groups of IAM subjects with the implementation of AM.Results: The results obtained were that six non-formal factors significantly impacted the six groups of IAM subjects. Six non-formal factors and six IAM subject groups were proven to influence the implementation of AM significantly and positively. The acceptance of this hypothesis is supported by several field practices that PT PLN Group has carried out to support the success of AM.Conclusions: The analysis results show that the transfer of knowledge and competence of human resources in 6 non-formal factors significantly influence the implementation of AM in PT PLN Group. Organizational culture and life cycle delivery factors of the Company in six IAM subject groups have the most dominant influence on the success of AM in PT PLN Group. The optimal implementation of AM at PT PLN Group can increase the nation's competitiveness by providing comprehensive and equitable electrical energy to the people of Indonesia.

This article investigates the adoption, simplification, and usage recommendations of the Indonesian Index of Learning Style Short Form (ILS-SF). The aim is to refine the initial Indonesian ILS, compare the suitability between engineering/non-engineering and high school/university, and assess their learning styles. The participants were 678 students (413 females), with an average age of 19.4±1.92 years. The methods used in this study were adopting the existing Indonesian version of ILS, simplifying–reducing the number of items, empirical verification (validity and reliability), and Indonesia data assessment. The results show that the original ILS could be simplified without sacrificing the quality of the model. On the contrary, validity and reliability measures have increased. Confirmatory Factor Analysis (CFA) supports a reduction from 44 to 15 items. It confirms the validity with favorable indices such as CFI (0.972), TLI (0.966), RMSEA (0.021), SRMR (0.049), and GFI (0.999)—Active-Reflective Cronbach's alpha at 0.507, Sensing-Intuitive at 0.590, and Visual-Verbal at 0.553. Indonesian ILS-SF is faster, simpler, more suitable for engineering than non-engineering, and more ideal for undergraduate than high school students. The analysis revealed that sensory (40.2%), active (18%), and visual (10.2%) preferences dominate among Indonesian students. This study highlights assessment tools tailored to diverse educational contexts.

Paper aims This study explores sustainability adoption in Indonesian construction firms by (a) describing current levels of the three sustainability pillars, (b) analyzing associations between key variables influencing sustainability performance, and (c) providing managerial insights and recommendations for improving sustainable construction practices in Indonesia.

The arrangement of street vendors is felt to be very important to create an orderly and comfortable atmosphere for the people of Medan Johor village. The chaotic and disorganized situation that occurred around the Medan Johor sub-district was caused by street vendors who were not well organized. To find out the implementation of the Minister of Home Affairs Regulation No. 41 of 2012 concerning Guidelines for the Empowerment of Street Vendors in Suka Maju Village, Medan Johor Subdistrict, this research was conducted. The focus of the research is on implementing the policy of the Minister of Home Affairs Regulation. Structuring the empowerment of street vendors requires evaluation and relocation. The purpose of this study is to determine the extent to which Ministerial Regulation No. 41 of 2012 is applied to the Suka Maju sub-district, Medan Johor sub-district. Data was collected through observational studies, interviews and documentation studies. Further analysis is carried out. The methodology in this research is descriptive qualitative. The results of the study show that there is a need for more optimal socialization. This study concludes that the relocation of street vendors in Suka Maju sub-district, Medan Johor sub-district has not run optimally and that many traders still do not want to be relocated to places that have been provided by the Suka Maju sub-district, Medan Johor sub-district.

Purpose: This research was conducted to analyze the extent to which online customer reviews (OCR_s) can stimulate investment backers as a strategy to increase crowdfunding investment. Design / Method / Approach: This research is quantitative. Natural language processing (NLP) processes review text documents based on linguistic study, a lexicon-based method is used for sentiment analysis classification based on polarity score (pros and cons), while Multiple linear regression forms a model or relationship between online customer reviews and crowdfunding investments. OCR_s consisting of numeric and text features were collected from one hundred technology products (3D printing, drones, cameras, wearables) on Kickstarter.com. Findings: The study results show that, in addition to positive reviews, the number of comments and the number of sentiment reviews can increase consumer interest in investing in technology products on the crowdfunding platform. Moreover, positive reviews have the most positive effect on crowdfunding investments. Practical Implications: The study results are expected to be used for startup business, especially technology products as a strategy to increase funding investment on a reward-based crowdfunding platform. Startups can take advantage of online customer reviews as one of important factors in stimulating potential backers and backers to invest. Social implications: The strategy of utilizing online customer reviews can be used especially for technology product-based startup business to get funding support as a resource in completing a product development stage. Originality / Value: The novelty of this research is that it focuses on a technological product development stage, product campaigns on a reward-based crowdfunding platform, considering online customer reviews through sentimental (online reviews) and numerical characteristics (number of comments, number of sentiment reviews) simultaneously as a strategy to increase investment. Research Limitations / Future Research: This study has some limitations as it used only online customer reviews as an attribute that affects crowdfunding investment. Future research is expected to explore online customer reviews to determine important attributes (unique words) as consideration for strategies to increase crowdfunding investment. Paper type: Empirical

Purpose: Rapid worldwide growth in megaprojects has attracted academic interest. In practice, complexity is one of the main causes for the failure of megaprojects. This study proposes a system of project manager leadership to overcome problems of complexity in achieving success with a megaproject.Design/methodology/approach: This study uses configuration analysis, fuzzy-set qualitative comparative analysis (fsQCA), to investigate the combination of complexity and leadership competencies that promote megaproject success. This study analyzes three megaproject manager leadership competencies—technical, emotional–social and adaptive—with three megaproject complexities—structural, social and emergent—to determine the combinations and levels required to ensure a megaproject’s short- and long-term success. Seven Indonesian infrastructure megaprojects were involved in this explorative study.Findings: This study has identified four combinations between complexity and leadership competencies and three necessary conditions that can lead to a successful megaproject. This study also reports that insufficient project manager leadership competence in the technical, emotional-social, and adaptive aspects can lead to lower megaproject performance.Research limitations/implications: By using fsQCA, this study is sufficient to understand the combination of complexity and leadership competencies in the megaproject performance. However, configuration comparative analysis using small samples is unable to explain results that are more rigorous when compared with the statistical approach. Having higher cases and additional analytical approaches that can lead to a more robust quantitative analysis method is strongly needed to address these limitations.Practical implications: For practitioners, this study proposes effective leadership competency combinations for managing various complexities of the megaproject.Originality/value: This study provides an insight into the competencies of megaproject management leadership. This study contributes to the literature by providing fresh perspectives on megaproject management, especially in terms of complexity and leadership. This is an important research area for the development of megaproject management theory as it fills theoretical gaps in megaproject management in terms of the leadership aspect.
